TECHNICAL FIELD

The present invention relates to a compound for an organic electronic element, an organic electronic element using the same, and an electronic device comprising the same.

BACKGROUND ART

In general, an organic light emitting phenomenon refers to a phenomenon in which electric energy is converted into light energy of an organic material using an organic material. An organic electronic element utilizing the organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer interposed therebetween. In many cases, the organic material layer may have a multilayered structure including multiple layers made of different materials in order to improve the efficiency and stability of an organic electronic element, and for example, may include a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, or the like.

A material used as an organic material layer in an organic electronic element may be classified into a light emitting material and a charge transport material, for example, a hole injection material, a hole transport material, an electron transport material, an electron injection material, and the like according to its function.

Further, the light emitting material may be divided into a high molecular weight type and a low molecular weight type according to its molecular weight, and may also be divided into a fluorescent material derived from electronic excited singlet states and a phosphorescent material derived from electronic excited triplet states according to its light emitting mechanism. Further, the light emitting material may be divided into blue, green, and red light emitting materials, and yellow and orange light emitting materials required for better natural color reproduction according to its light emitting color.

When only one material is used as a light emitting material, there occur problems of shift of a maximum luminescence wavelength to a longer wavelength due to intermolecular interactions and lowering of the efficiency of a corresponding element due to the deterioration in color purity or a reduction in luminous efficiency. On account of this, a host/dopant system may be used as the light emitting material in order to enhance the color purity and increase the luminous efficiency through energy transfer. This is based on the principle that if a small amount of dopant having a smaller energy band gap than a host forming a light emitting layer is mixed in the light emitting layer, then excitons generated in the light emitting layer are transported to the dopant, thus emitting light with high efficiency. With regard to this, since the wavelength of the host is shifted to the wavelength band of the dopant, light having a desired wavelength can be obtained according the type of the dopant.

Currently, the power consumption is required more and more as the size of display becomes larger and larger in the portable display market. Therefore, the power consumption is a very important factor in the portable display with a limited power source of the battery, and efficiency and life span issue also is solved.

Efficiency, life span, driving voltage, and the like are correlated with each other. For example, if efficiency is increased, then driving voltage is relatively lowered, and the crystallization of an organic material due to Joule heating generated during operation is reduced as driving voltage is lowered, as a result of which life span shows a tendency to increase. However, efficiency cannot be maximized only by simply improving the organic material layer. This is because long life span and high efficiency can be simultaneously achieved when an optimal combination of energy levels and T1 values, inherent material properties (mobility, interfacial properties, etc.), and the like among the respective layers included in the organic material layer is given.

That is, in order to allow the organic electronic element to sufficiently exhibit excellent characteristics, most of all, materials constituting an organic material layer in the element, for examples, a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material, and the like need to be supported by stable and efficient materials, but the development of stable and efficient materials for the organic material layer for an organic electronic element is not sufficiently achieved. Therefore, the development of new materials is continuously required, and especially, the development of an electron transport material and a light emitting material is urgently required.

The Figure illustrates an organic electronic element according to an embodiment of the present invention.

Referring to the Figure, an organic electronic element 100 according to an embodiment of the present invention includes a first electrode 120 formed on a substrate 110, a second electrode 180, and an organic material layer between the first electrode 120 and the second electrode 180, which contains the compound of the present invention. Here, the first electrode 120 may be an anode (positive electrode), and the second electrode 180 may be a cathode (negative electrode). In the case of an inverted organic electronic element, the first electrode may be a cathode, and the second electrode may be an anode.

The organic material layer includes a hole injection layer 130, a hole transport layer 140, a light emitting layer 150, an electron transport layer 160, and an electron injection layer 170 formed in sequence on the first electrode 120. Here, the layers included in the organic material layer, except the light emitting layer 150, may not be formed. The organic material layer may further include a hole blocking layer, an electron blocking layer, an auxiliary light emitting layer 151, a buffer layer 141, etc., and the electron transport layer 160 and the like may serve as the hole blocking layer.

Although not shown, the organic electronic element according to an embodiment of the present invention may further include a protective layer or a light efficiency improving layer (capping layer) formed on at least one of the sides the first and second electrodes, which is a side opposite to the organic material layer.

The compound of the present invention employed in the organic material layer may be used as a host material, a dopant material, or a light efficiency layer material in the hole injection layer 130, the hole transport layer 140, the electron transport layer 160, the electron injection layer 170, the auxiliary light emitting layer 151, or the light emitting layer 150. Preferably, the compound of the present invention may be used for the hole transport layer 140 and the auxiliary light emitting layer 151.

Since depending on the type and position of a substituent to be attached, a band gap, electrical properties, interfacial properties, and the like may vary even in the same core, it is very important what the types of core and a combination of substituent attached to the core are. Specially, long life span and high efficiency can be simultaneously achieved when an optimal combination of energy levels and T1 values, inherent material properties (mobility, interfacial properties, etc.), and the like among the respective layers included in the organic material layer is given.

Accordingly, in the present invention, energy levels and T1 values and inherent material properties (mobility, interfacial properties, etc.), and the like among the respective layers included in the organic material layer are optimized by forming a hole transport layer and an auxiliary light emitting layer using the compound represented by formula 1, and thus the life span and efficiency of the organic electronic element can be improved at the same time.

An organic light emitting diode according to an embodiment of the present invention may be manufactured using a physical vapor deposition (PVD) method. For example, the organic electronic element may be manufactured by depositing a metal, a metal oxide having conviducive, or an alloy thereof, on the substrate to form the anode 120, forming the organic material layer including the hole injection layer 130, the hole transport layer 140, the auxiliary light emitting layer 151, the light emitting layer 150, the electron transport layer 160, and the electron injection layer 170 thereon, and then depositing a material, which can be used as the cathode 180, thereon.

Also, the organic material layer may be manufactured in such a manner that a smaller number of layers are formed using various polymer materials by a soluble process or solvent process, for example, spin coating, dip coating, doctor blading, screen printing, inkjet printing, or thermal transfer, instead of deposition. Since the organic material layer according to the present invention may be formed in various ways, the scope of protection of the present invention is not limited by a method of forming the organic material layer.

According to used materials, the organic electronic element according to an embodiment of the present invention may be of a top emission type, a bottom emission type, or a dual emission type.

A WOLED (White Organic Light Emitting Device) readily allows for the formation of ultra-high definition images, and is of excellent processability as well as enjoying the advantage of being produced using conventional color filter technologies for LCDs. In this regard, various structures for WOLEDs, used as back light units, have been, in the most part, suggested and patented. Representative among the structures are a parallel side-by-side arrangement of R (Red), G (Green), B (Blue) light-emitting units, a vertical stack arrangement of RGB light-emitting units, and a color conversion material (CCM) structure in which electroluminescence from a blue (B) organic light emitting layer, and photoluminescence from an inorganic luminescent using the electroluminescence are combined. The present invention is applicable to these WOLEDs.

For example, when o, m, and n are each 1, L¹, L², and L³ may be a single bond, a phenylene group, a biphenylene group, a naphthyl group, a fluorenyl group, a heterocyclic group. Herein, the meaning of “when o, m, and n are each 1, L¹, L², and L³” is that “L¹ when o is 1, L² when m is 1, and L³ when n is 1” and includes both a case where only one of o, m, and n is 1 and a case where two of o, m, and n are 1.

MANUFACTURING AND EVALUATION OF ORGANIC ELECTRONIC ELEMENT Example 1 Green Organic Light Emitting Diode (Hole Transport Layer)

An organic light emitting diode was manufactured by an ordinary method using the compound of the present invention as a material for a hole transport layer. First, 4,4′,4″-Tris[2-naphthyl(phenyl)amino]triphenylamine (hereinafter, abbreviated as “2-TNATA”) was vacuum-deposited to a thickness of 60 nm on an ITO layer (anode) formed on a galas substrate to form a hole injection layer, and then, compound P 1-1 of the present invention was vacuum-deposited to a thickness of 60 nm on the hole injection layer to form a hole transport layer. Subsequently, 4,4′-N,N′-dicarbazole-biphenyl (hereinafter, abbreviated as “CBP”) as a host material and tris(2-phenylpyridine)-iridium (hereinafter, abbreviated as “Ir(ppy)₃”) as a dopant material were doped at a weight ratio of 90:10 and thus vacuum-deposited to a thickness of 30 nm on the hole transport layer to form a light emitting layer. Then, a film of (1,1′-bisphenyl)-4-olato)bis(2-methyl-8-quinolinolato) aluminum (hereinafter, abbreviated as “BAlq”) was vacuum-deposited to a thickness of 10 nm on the light emitting layer to form a hole blocking layer, and tris(8-quinolinolato)aluminum (hereinafter abbreviated as “Alq₃”) was vacuum-deposited to a thickness of 40 nm on the hole blocking layer to form an electron transport layer. Thereafter, LiF as a halogenated alkali metal was deposited to a thickness of 0.2 nm to form an electron injection layer, and then Al was deposited to a thickness of 150 nm to form a cathode, and ultimately, an organic light emitting diode was manufactured.

As can be seen from the results of table 4 above, it was verified that the organic light emitting diodes using the inventive compounds as a material for a hole transport layer showed a low driving voltage, comparatively high efficiency, and a high lifetime compared with comparative compound 1 and comparative compound 2.

Especially, comparative compound 2, which has a similar structure to the inventive compounds of the present invention in view of a core region, showed comparatively high efficiency, but showed a significantly lower lifetime compared with the inventive compounds of the present invention.

The reason is determined that the element lifetime of comparative compound 2 showed a similar pattern to those of the inventive compounds of the present invention at the initial stage of element driving and then was rapidly decreased, and in most cases, the decrease in the element lifetime occurs due to joule heat (the occurrence of thermal damage) or the charge unbalance in the light emitting layer. As can also be seen from the measurement results of the elements using the inventive compounds of the present invention, the functional difference depending on the number of amine groups binding to a core of the inventive compound of the present invention can be found. It is determined that the increase in the number of amine groups induces more rotation points in the molecule, resulting in a reduction in packing density, causing a deterioration in hole mobility.

Example 276 Green Organic Light Emitting Diode (Hole Transport Layer +Auxiliary Light Emitting Layer)

An organic light emitting diode was manufactured by an ordinary method using the compound of the present invention as a material for a hole transport layer. First, a film of N¹-(naphthalen-2-yl)-N⁴,N⁴-bis(4-(naphthalen-2-yl(phenyl)amino)phenyl)-N¹-phenylbenzene-1,4-diamine (hereinafter, abbreviated as “2-TNATA”) was vacuum-deposited on an ITO layer (anode} formed on a galas substrate, to form a hole injection layer with a thickness 60 nm. Then, compound P 1-40 of the present invention was vacuum-deposited to a thickness of 60 nm on the hole injection layer to form a hole transport layer. Then, the inventive compound (among compound P 1-59 and 12 kinds of other compounds) as a material for an auxiliary light emitting layer was vacuum-deposited to a thickness of 20 nm to form an auxiliary light emitting layer. After the auxiliary light emitting layer was formed, CBP [4,4′-N,N′-dicarbazole-biphenyl] as a host material and Ir(ppy)₃ [tris(2-phenylpyridine)-iridium] as a dopant material were doped at a weight ratio of 95:5 on the auxiliary light emitting layer, so that, a light emitting layer with a thickness of 30 nm was deposited on the auxiliary light emitting layer. Then, (1.1′-bisphenyl)-4-olato)bis(2-methyl-8-quinolinolato) aluminum (hereinafter abbreviated as “BAlq”) was vacuum-deposited to a thickness of 10 nm for a hole blocking layer, and a film of tris(8-quinolinol)aluminum (hereinafter abbreviated as “Alq₃”) was formed with a thickness of 40 nm for an electron transport layer. Thereafter, LiF as halogenated alkali metal was deposited to a thickness of 0.2 nm for an electron injection layer, and then Al was deposited to a thickness of 150 nm and used as a cathode, and ultimately, an organic light emitting diode was manufactured.

Example 277 to Example 288 Green Organic Light Emitting Diode (Hole Transport Layer +Auxiliary Light Emitting Layer)

Organic light emitting diodes were manufactured by the same method as in Example 276 except that, instead of inventive compound P 1-59, the inventive compounds shown in table 8 below were used as a material for an auxiliary light emitting layer.

A forward bias DC voltage was applied to each of the manufactured organic light emitting diodes of the examples and comparative examples to measure electroluminescent (EL) characteristics thereof by PR-650 from Photoresearch Company, and on the basis of the measurement results, the T95 lifetime was measured by lifetime measuring equipment from Mcscience Company at a standard brightness of 5000 cd/m². Table 8 below shows the manufacturing of elements and evaluation results thereof.

As can be seen from the results of tables 5, 6, 7, and 8, it can be verified that the use of the inventive materials for the organic light emitting diode for an auxiliary light emitting layer significantly improved the light emission efficiency and lifetime, and it can be verified that the use of the inventive compounds for a hole injection layer and an auxiliary light emitting layer significantly improved the lifetime of the organic light emitting diodes.

In other words, it can be verified that the efficiency and lifetime were improved when the auxiliary light emitting layer was used than when the auxiliary light emitting layer was not used, and it can be verified that a higher efficiency and a higher lifetime were showed when the inventive compounds of the present invention, rather than comparative compounds 1 and 2, were used for the auxiliary light emitting layer.

The reason that the use of the inventive compounds of the present invention for an auxiliary light emitting layer induced higher increased efficiency is determined that deep HOMO energy levels reduce the excessive supply of holes into the light emitting layer, thereby increasing the charge balance in the light emitting layer and reducing the entry of excessive holes into the electron transport layer, thus increasing the efficiency.

It is also determined that the auxiliary light emitting layer has a relatively high T1 value, thereby preventing the entry of excessive electrons into the hole transport layer, thus reducing the deterioration in color purity and the thermal damage caused by light emission in the hole transport layer, leading to an increase in the lifetime.

From the results of comparative examples 4, 5, 7, 8, 10, and 11 using comparative compounds 1 and 2 for an auxiliary light emitting layer, it can be verified that comparative examples 4, 5, 7, 8, 10, and 11 showed small increases in efficiency and lifetime but an increasing driving voltage compared with when the auxiliary light emitting layer was not used.

Last, it can be seen verified through the comparison between tables 5 and 8 that the lifetime was increased when inventive compound P 1-40 of the present invention was used for the hole transport layer and inventive compound P 1-59 and 12 other inventive compounds were used for the auxiliary light emitting layer than when comparative compound 1 was used for the hole transport layer.

In addition, the characteristics of elements have been described in view of a hole transport layer and an auxiliary light emitting layer in the foregoing evaluation results of the manufacturing of elements, but ordinarily, the materials used for a hole injection layer and an auxiliary light emitting layer may be used alone or in a mixture with other materials, for the foregoing organic material layer for layers of an organic electronic element, such as an electron transport layer, an electron injection layer, a hole injection layer, and a light emitting layer. Therefore, for the foregoing reasons, the inventive compounds may be used alone or in a mixture with other materials, for, in addition to the hole transport layer and the auxiliary light emitting layer, the other layers of an organic material layer, for example, an electron transport layer, an electron injection layer, a hole injection layer, and a light emitting layer.

Although exemplary embodiments of the present invention have been described for illustrative purposes, a person skilled in the art will appreciate that various modifications, additions, and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. Therefore, the embodiment disclosed in the present invention is intended to illustrate the scope of the technical idea of the present invention, and the scope of the present invention is not limited by the embodiment. The scope of the present invention shall be construed on the basis of the accompanying claims, and it shall be construed that all of the technical ideas included within the scope equivalent to the claims belong to the present invention.
